Method and system for screen correction

Abstract

A method, system, and a computer readable medium for screen correction is provided. The system includes a memory storage unit for storing model content, a screen having screen parameters, an input device for receiving the screen parameters, a correction engine, and a projector. The method involves storing model content on a memory storage unit, receiving screen parameters, generating screen content, and projection at least a portion of the screen content onto the screen. The computer readable medium encoded with codes for directing a processor to carry out the method.

What is claimed is: 
     
       1. A system for screen correction, the system comprising:
 a memory storage unit for storing content provided by a content producer, wherein the content provided by the content producer is rendered to be displayed in accordance with given model parameters; 
 a screen having screen parameters; 
 an input device configured to receive the screen parameters, wherein the input device periodically scans the screen to determine the screen parameters; 
 a correction engine in communication with the memory storage unit and the input device, the correction engine configured to process the content provided by the content producer and the screen parameters to generate screen content; and 
 a first projector in communication with the correction engine, the first projector configured to receive a first portion of the screen content and to project the first portion the screen content onto the screen. 
 
     
     
       2. The system of  claim 1 , further comprising a second projector in communication with the correction engine, the second projector configured to receive a second portion of the screen content and to project the second portion of the screen content onto the screen, wherein the first portion of the screen content and the second portion of the screen content overlap on the screen. 
     
     
       3. The system of  claim 2 , wherein the screen is non-planar. 
     
     
       4. The system of  claim 3 , wherein the screen is curved. 
     
     
       5. The system of  claim 1 , wherein the screen includes a plurality of topographical reference points. 
     
     
       6. The system of  claim 5 , wherein the plurality of topographical reference points defines a plurality of facets. 
     
     
       7. The system of  claim 1 , wherein the input device is a camera configured to measure the screen parameters. 
     
     
       8. The system of  claim 7 , wherein the camera measures the screen parameters using a calibration pattern projected by the first projector. 
     
     
       9. The system of  claim 1 , wherein the input device is a 3D scanning unit. 
     
     
       10. A method of screen correction, the method comprising:
 storing content provided by a content producer on a memory storage unit, wherein the content provided by the content producer is rendered to be displayed in accordance with given model parameters; 
 scanning a screen to determine screen parameters periodically with an input device; 
 receiving, at a correction engine, the screen parameters of the screen from the input device; 
 generating screen content by processing the content provided by the content producer and the screen parameters at the correction engine; and 
 projecting at least a first portion the screen content onto the screen using a first projector in communication with the correction engine. 
 
     
     
       11. The method of  claim 10 , further comprising projecting a second portion of the screen content onto the screen using a second projector in communication with the correction engine, wherein the first portion of the screen content and the second portion of the screen content overlap on the screen. 
     
     
       12. The method of  claim 11 , wherein projecting the first portion and the second portion of the screen content the screen comprises projecting on a non-planar surface. 
     
     
       13. The method of  claim 10 , further comprising defining a plurality of facets using a plurality of topographical reference points on the screen. 
     
     
       14. The method of  claim 10 , wherein receiving the screen parameters comprises measuring the screen parameters with the input device. 
     
     
       15. The method of  claim 14 , further comprises projecting a calibration pattern to measure the screen parameters. 
     
     
       16. The method of  claim 10 , wherein the input device is a camera. 
     
     
       17. The method of  claim 10 , wherein the input device is a 3D scanning unit. 
     
     
       18. A non-transitory computer readable medium encoded with codes, the codes for directing a processor to:
 store content provided by a content producer on a memory storage unit, wherein the content provided by the content producer is rendered to be displayed in accordance with given model parameters; 
 scan a screen to determine screen parameters periodically with an input device; 
 receive the screen parameters of the screen from the input device; 
 generate screen content by processing the content provided by the content producer and the screen parameters at a correction engine; and 
 project at least a first portion the screen content onto the screen using a first projector in communication with the correction engine.
